Do Lithium Batteries Last Longer Than Lead Acid

[This review was collected as part of a promotion.] I’ve had this running for a couple weeks now and couldn’t be happier. I’ve installed this quite easily in my wall rack and have to say I am very happy with it’s performance and solid build quality. It’s as plug and play as you’re going to get. I find myself often looking over to see that it running as it’s very quiet and the fan only turns on when the load get’s to a certain levelEven then I just don’t hear it. Seems to be very efficient with low heat. This unit also has the lithium-ion battery and seems to weigh less than half the weight (just over 30lbs) of my older lead acid battery unit and smaller in overall size. In the long run I feel it’s going to be much more cost effective replacing the lithium-ion battery over time as they’re just getting cheaper and last longer than the older lead acid batteries. From an aesthetics point of view, I feel the unit is nicely designed and appealing. The multi-function LCD is easy to use and view various in-depth metrics. If you’re in the market looking for a smart ups or to replace a older lead acid unit then I highly recommend the APC smart-ups. Good quality brand and dependability.

My old lead acid batteries are 4 years old and expect they will start to fail. I bought the delta 2 so I could transition to lithium batteries. So far it has been a very good and simple project. I like that it has it's own charge controller with a few different ways to charge. So far so good. Will probably buy the extra battery eventually.

GREAT PRODUCT. BETTER THAN MY LAST ONE.

Last longer than others.

Last's much longer than generic

Much superior to alkaline batteries for use in my portable flash. Last longer, cycle faster.

These lithium batteries are very lightweight and last much longer than traditional. Great for on-camera flash where I don't want a lot of weight.

As stated in the headline, it works, charges slower so the lithium-ion batteries last longer. I have the fast charger but bought this to condition the batteries over time. Fast charging all the time will shorten the life of your $$ battery.

Love the lithium battery. Lasts so much longer than all the alkaline batteries I was using and best of all it saves me gas on all the trips I don't have it make to change those alkaline batteries.

This lithium batteries cost more, quite a bit more; but the upside is far longer service and MOST important!!, they will NOT corrode inside your devices when discharged as most Alkaline types will eventually destroying the battery contact terminals or worse!!
